Husababu wa kufungua hekima ya kufichwa

Kielele 1 - Ongeza HTML:

<button onclick="document.getElementById('id01').style.display='block'">Open Modal</button>
<div id="id01" class="modal">
  <span onclick="document.getElementById('id01').style.display='none'" class="close" title="Close Modal">×</span>
  <form class="modal-content" action="/action_page.php">
    <div class="container">
      <h1>Delete Account</h1>
      <p>Are you sure you want to delete your account?</p>
      <div class="clearfix">
        <button type="button" class="cancelbtn">Cancel</button>
        <button type="button" class="deletebtn">Delete</button>
      </div>
    </div>
  </form>
</div>

第二步 - 添加 CSS：

* {box-sizing: border-box}
/* 为所有按钮设置样式 */
button {
  background-color: #04AA6D;
  color: white;
  padding: 14px 20px;
  margin: 8px 0;
  border: none;
  cursor: pointer;
  width: 100%;
  opacity: 0.9;
}
button:hover {
  opacity:1;
}
/* 使取消和删除按钮浮动，并添加相等的宽度 */
.cancelbtn, .deletebtn {
  float: left;
  width: 50%;
}
/* 为取消按钮添加颜色 */
.cancelbtn {
  background-color: #ccc;
  color: black;
}
/* 为删除按钮添加颜色 */
.deletebtn {
  background-color: #f44336;
}
/* 为容器添加内边距并居中文本 */
.container {
  padding: 16px;
  text-align: center;
}
/* 模态（背景） */
.modal {
  display: none; /* 默认隐藏 */
  position: fixed; /* 固定在原地 */
  z-index: 1; /* 置于顶层 */
  left: 0;
  top: 0;
  width: 100%; /* 全宽 */
  height: 100%; /* 全高 */
  overflow: auto; /* Inafaa kufungua uharibifu (kama inahitajika) */
  background-color: #474e5d;
  padding-top: 50px;
}
/* Kijifunzi cha ikona au ikona ya modal */
.modal-content {
  background-color: #fefefe;
  margin: 5% auto 15% auto; /* Kijumuiya kwenye mabara ya juu 5%, kwenye mabara ya chini 15%, na kumekadiri kwa 5% */
  border: 1px solid #888;
  width: 80%; /* Kijumuiya kwamba inaweza kuwa zaidi au zaidi kubwa, bila ya kijumuiya kijani */
}
/* Kuhariri stili ya mstari wa kijani */
hr {
  border: 1px solid #f1f1f1;
  margin-bottom: 25px;
}
/* Butoni la kufunga ikona ya modal (x) */
.close {
  position: absolute;
  right: 35px;
  top: 15px;
  font-size: 40px;
  font-weight: bold;
  color: #f1f1f1;
}
.close:hover {
.close:focus {
  color: #f44336;
  cursor: pointer;
}
/* Tukidhahili mafanikio ya mafunzo */
.clearfix::after {
  content: "";
  clear: both;
  display: table;
}
/* kuhariri stili ya butoni ya kufungua na butoni ya kufa kwenye skrini ya kidogo */
@media screen and (max-width: 300px) {
  .cancelbtn, .deletebtn {
    width: 100%;
  }
}

亲自试一试

Tahadhi:Inafaa tumie machapisho ya JavaScript hii, kufunga ikona ya modal kwa kusikitisha kwenye eneo la kijifunzi cha ikona hili (hakuna sababu ya kufunga ikona hili kwa kusikitisha kwenye x au butoni la kufungua):

mifano

<script>
// pata ikona ya modal
var modal = document.getElementById('id01');
// ingawa hili mtu anasikitisha kwenye ikona ya modal yana kufunga
window.onclick = function(event) {
  if (event.target == modal) {
    modal.style.display = "none";
  }
}
